gnomesu

I apologise if this has been discussed and I've missed it, but what's happened to "gnomesu" (or gtksu)? I cannot run YaST from Gnome - it complains about gnomesu missing, though occasionally, not always, kdesu will pop up. Usually though, I have to run the ncurses version in a terminal. There don't seem to be any recent versions of gnomesu available. David
